BOOT-CRIMP.

Specification of Letters Patent No. 8,305, dated .August 19, 1851.

T0 all whom, t may concern:

Be it known that I, I-IARTwELIa STANLEY, of IVilmington, county ofVindham, and State of Vermont, have invented a new and Improved Mode ofCrimping Boots; and I do declare that the following is a full and exactdescription thereof, referencev being had to the accompanying drawingsand to the letters of reference marked thereon.

Plate lst in the drawings represent the vmachine in position to receivethe boot front for crimping. Y

A A, is the crimp board on which the boot front is crimped.

B, B, is the brake which is drawn down over the crimp board to crimp theboot front.

I, is a long screw with a crank on the end, at P, passing through thebolt, O, and lying in a slot in the top of the crimp at P for thepurpose of drawing the top of the brake over the crimp board 4by turningthe crank.

O, is a lever attached by a joint to the toe of the crimp board spanningit and the toe of the brake also spanning the lever. M, a bolt or screwpassing through the toe of the brake; the end of the lever; and also thetoe of the crimp board holding them all in their proper places while inoperation.

E is a knob on the brake for the purpose of carrying forward the leverO, when the brake is drawn down far enough for the knob to strike a boltpassing through the lever C at G, thereby moving the lower end of thelever O in the direction of the arrow.

D D D is the circulargroove in the crimp board in which are placed thetwo circular rods E E connected by cogs or gear as represented in thedrawings, one of which rods is attached to the lever O at Q. On the endof the other at E is a bolt or screw passing through into the clamps I-Ithat receives the corner of the boot front as they are` drawn over thecrimp board A A.

N is a bolt or screw passing through the braketo adjust them to a properdistance to pass over the crimp board.

O is another bolt or screw passing through the top of the brakeadjusting it as before described and at the same time receives the screwI by which the brake is drawn over the crimp board.

P is a projection on the top of the crimp board which has a slot in itthrough which the screw I is pierced in drawing the brake down over thecrimp board.

Plate 2nd marked K is a plate fitting the circular groove in the crimpboard covering the circular rods E E over smoothly making the crimpboard A A smooth on the outer surface, to draw the boot front over whilethe rods perform their service acting in the center of the crimp board.

The operation of the machine is as follows: Then Plate 2nd marked K' isplaced on the circular grooves and fastened there and the machine inposition indicated in the drawings throw forward the brake and lay theboot front on to the crimp board in position for crimping drawing thecorners and placing them in the clamps H then apply the hand to thecrank J and draw the brake over on the crimp board till the knob itforward in the direction of the arrow and by this means drawing theopposite rod with its head E in thel direction of the arrow and thusbringing the corners of the boot front all down together and at the sametime by turning the screw I.

What I claim as my invention and desire to secure by Letters Patent is-The lever C, the knob F, the bolt, G, and the two circular rods E E incombination with each other and with the other parts of the machine asdescribed for the purpose of drawing the corners of the front to theirproper place at the same time the brake is passing down over it byturning the screw I, and I make no further claim.
